stems 52, 53 slidable in bearings 54, attached to the cylinder 10. The outer ends of the valve stems 52, 53 are provided with .friction rollers 55, 56 in engagement with the peripheral faces of cams 57 and 58 secured on a shaft 51) journaled in suitable bearings 60 attached to the cylinder 10. The springs 61 press the stems 52. and 53 in an outward direction to hold the friction rollers,55, 56 in peripheral engagement with the cams 57 and 58.

The abutment; wheel 18 is locked against rotation until the piston head 16 nears the arm 17 in position at the time in the `work ing chamber 15, and then the abutment wheel 18 is automatically unlocked to allow the piston head 16 to turn the abutment wheel 18. This locking device for the abut-- ment wheel 18 consists of a wheel 62 secured on the shaft 19 outside of the casing 20, and this Wheel 62 is provided with notches 63 adapted to be engaged by a springpressed bolt 64 .mounted to slide in bearings arranged on a bracket 65 attached to or forming part of the cylinder 10. The springpressed bolt 64 is provided with a pin 66 slidably engaging a slot 67 formed in the bracket 65 to hold the bolt 64 against turning. The pin 66 is adapted to be engaged by a, cam lug 70 secured on a sprocket wheel 71 mounted to rotate loosely en the shaft 19.

Around the sprocket wheel 71 passes a' sprocket chain 72which also passes around a sprocket wheel 73 secured on the rotor sha t 13 and the sprocket chain 72 also passes around a sprocket wheel 74 secured on the cam shaft 59, previously mentioned. When the motor is running and the rotor 12 rotates in the direction of the arrow a then a-traveling motion is given to the sprocket chain 72 in the direction of the arrow b whereby the sprocket wheel 71 is turned in the direction of the arrow, c and its cam lug 70 periodically strikes the pin 66 and thereby moves the bolt 64 out of engagement with the corres onding notch 63 at the time the piston hea 16 nears the arm 17 in position at the time in the working chamber 15. Thus the abutment wheel 18A is unlocked to allow the piston head 16 to turn the abutment wheel 18 and thus bring t-he next Vfollowing arm 17 in position in the working chamber 15. The piston head 16 after passin the arms 17 also passes the -inlet end of t e pressure supply and ignition chamber 25 so that. the explosive mixture passes from this chamber 25 into the working chamber and is at the Sametime ignited by the ignition device 26 to cause therotor 1 2 to receive an impulse and thus be driven in the direction of the arrow a. An exhaust pipe leads from the cylinder 10 adjacent the side of the casing 2O opposite the one at which the chamber 25 is locked so that the products of combustion in front of the istonA head 16 'can escape to a suitable p ace of discharge.

The abutment wheel 18 is preferably pro! cilinder, ormmg with the cylinder an annular working chamber, the rotor having a piston head, an abutment wheel having arms ada ted to move successively into the said wor ing chamber and adapted to be enga ed by the said piston head, locking means or locking thesaid abutment wheelagainst turning, driving means driven from the said rotor controllin the said lockin means to unlock the said abutment whee prior to the pistonheadcam shaft having arms controlling the Said valve stems and valves, and driving means for driving the saidcam sh'aft and controlled from the said rotor, the said driving means for the abutment wheel and the said driving means for the said cam shaft having a driving member common to both. 2. A rotary engine, comprising a c linder, a rotor mounted to turn therein and orming with the cylinder an annular working chamber, the rotor having a piston head, an abutment wheel haring arms adapted to move successively into the said working chamber and adapted to be engaged by the said piston head, locking means for locking the said abutment wheel against turning, drivin means driven from thesaid rotor contro ling the said locking means to unlock-the said abutment wheel prior to the piston head reachin `the abutment arm in position in the wor in chamber at the time, a pressure supply an ignition chamber opening into the said working chamber adjacent the abutment wheel, a gas chamber connected with a gas supply and having a port leading into the said pressure supv y and ignition chamber, an air chamber aving a port opening into the said pressure supply and ignition chamber, valves controlled from the rotor ports i iis vund controlling the, said ports, and manually contrnlled setting meanS in the said gas chamber and the smidv niry chamber for regw lnting thv gas und air passing into `the said gals und nil.' clmnflbers and 'mto the said sup ply und ignition chamber;
